Patented Dec. 24, 1929 UNITED STATES JAMES C. LYLE, OF PLYMOUTH, MASSACHUSETTS ROTARY MIXER Application filed October 14, 1927. Serial 210.226.211.

This invention relates to mixing devices for internal combustion engines and has for an object the provision of means operated by the suction of the engine which will break up the film of the vapor bubbles, so as to release the gas and mix the same with air and lower the temperature of the incoming fuel charge, and thus increase expansion when an explosion occurs, with a proportionate increase in the efiiciency of the engine and a corresponding decrease in fuel consumption.

Another object of the invention is the provision of a device which is controlled by the speed of operation of the engine and which will assist in the feeding of fuel to the engine cylinder, by assisting the next incoming charge.

Another object of the invention is the provision of a device which in addition to the above stated and other advantages, will provide an eflicient fuel mixing and agitating device capable of being readily installed for use.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a sectional View illustrating the invention.

Figure 2 is a detail plan view of the fan.

Figure 3 is an end view of one of the cylinder sections.

Figure 4 is a similar view of the other cylinder section.

Referring to the drawings in detail whercin like characters of reference denote corresponding parts, the device which is designed to be positioned between the end of the intake manifold 10 of an internal combustion engine and the adjacent end of the carbureter 11 of said engine, comprises a cylinder which is formed of inner and outer sections 12 and 13 respectively. These sections are adapted to be telescopically connected and for this purpose. the inner section is of less diameter than the outer section and the sections are slidable with respect to one another. The outer edge of the outer section and the outer edge of the inner section abut annular shoulders 14 provided upon each section.

Each of the sections is provided with an ear 15 which extends radially around its outer edge and these ears are provided with openings 16 which are adapted to be brought into register with openings 17 provided in the 0 ears 18 of the intake manifold and the ear 19 of the carbureter. Bolts 20 are adapted to extend through the ears 15, 18 and 19, and these bolts are threaded at opposite ends for the reception of nuts 21. The cylinder may ca thus be secured between the adjacent ends of the manifold and carbureter, being held in position by the bolts 20 which also serve to hold the sections 12 and 13 assembled.

A gasket 22 is preferably provided between the flanges at each end of the cylinder.

One of the sections, for example, the inner section 12 is provided with a bar or spider 23 which extends diametrically of the section and which is provided with a threaded 7 opening 24 for the reception of the threaded end of a bolt 25. This bolt is provided with a relatively large head 26 and a binding nut 27, the latter bearing against the bar 23. Rotata-bly mounted upon the bolt is a fan 28 and arranged between the opposite ends of the hub 29 of this fan, and the head 26 and the nut 27, are anti-friction devices 30. These anti-friction devices may be in the form of cage carried balls which bear against the i sleeve and the under face of the bolt head and the upper face of the nut 27. The fan is thus permitted free rotary movement. The bar 23 is preferably spaced inward from the lower end of the section 12 to permit of free operation of the usual butterfly valve 31 of the carbureter.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is In a mixing device, a housing formed of separable inner and outer telescopic sections, stop shoulders to limit relative inward movement of said sections, a bar carried by and extending diametrically across one section, a headed bolt threadedly engaged through the bar and disposed axially of the housing, a fan mounted for rotation upon the bolt a jamb nut mounted upon the bolt and bearing upon the bar, an anti-friction device interosed between the hub of the fan and the head of the bolt and between the hub of the fan and the j amb nut.

In testimony whereof I afiix my signature.

JAMES C. LYLE.
